2 medium zucchini, sliced into ½-inch thick half moons
1 medium yellow summer squash, sliced into ½-inch thick half moons
1 medium red, yellow or orange bell pepper, stem and seeds removed, cut into 1-inch chunks
1 cup cherry or grape tomatoes, halved
1 medium red onion, cut into 1-inch chunks
kosher salt and black pepper
¼ cup plus 1 tablespoon extra virgin olive oil, divided
3 tablespoons balsamic vinegar, divided
juice of 1 lemon
1½ lbs shrimp, peeled and deveined (tails left on, if desired)
½ teaspoon Worcestershire sauce
¼ cup roughly chopped basil leaves

Place one oven rack in the center of the oven, and the other rack 4 inches from the top heat. Spray a sheet pan with cooking spray. Preheat the oven to 375ºF. Combine the zucchini, yellow squash, bell pepper, tomatoes, and onion on the prepared sheet pan and season with ½ teaspoon salt, ½ teaspoon pepper, ¼ cup of the olive oil, 2 tablespoons of the vinegar and the lemon juice. Toss to coat. Roast the vegetables on the center rack until they are softened and they are beginning to brown on the edges, about 20-25 minutes. Remove the sheet pan from the oven. While the vegetables are cooking, place the shrimp in a large bowl and add ¼ teaspoon salt, the remaining 1 tablespoon of olive oil, the remaining 1 tablespoon of vinegar, and the Worcestershire sauce. Toss gently. Let the shrimp marinate at room temperature while the vegetables are roasting. Once you remove the vegetables from the oven, turn the oven to broil. Scatter the shrimp and the marinade over the vegetables in a single layer. Broil on the upper rack in the oven until the shrimp are cooked through, about 5 minutes. Scatter the basil over the finished dish. Serve with bread or a side of couscous.
